Halo2 Xbox tip details

Burst fire of dual SMG's

You can eliminate the recoil and increase the accuracy of the dual smg combo by rapidly alternating the two triggers in a L-R-L-R-L-R-L-R fashion quickly to fire. It is still better to lay into both at extreamely close range since the increased accuracy won't make up for the drop in rate of fire as much the closer you get. When you learn to alternate triggers slower the closer you get to your enemy and then lay into them when you are right next to them you can kill fairly well with the combo. It works for the PR/SMG combo as well but the shots on the PR are more innacurate at longer range.
